Nyengo ku China tsopano yayamba kuzizira, koma ntchito zopangira Jinbin Valve Factory zikadali zosangalatsa. Posachedwapa, fakitale yathu yamaliza maoda ambiri a ductile iron soft.mavavu otsekera zipata, zomwe zapakidwa ndi kutumizidwa kupita komwe zikupita.

Mfundo yogwirira ntchito ya chisindikizo chofewa cha ductile chitsulovalavu ya chipata cha wedgeKutengera kapangidwe kake kapadera ndi zipangizo zomwe zimagwiritsidwa ntchito. Gawo lalikulu la valavu iyi ndi chipata, chomwe chimakulungidwa ndi rabala yapadera yonse. Pakagwiritsidwa ntchito, tsinde la valavu limazunguliridwa kuti lisunthe chipatacho mmwamba ndi pansi, motero kudula kapena kulumikiza madzi omwe ali mupaipi. Malo awiri otsekera chipata nthawi zambiri amapanga mawonekedwe a wedge, ndipo kukula kwa ngodya ya wedge kumasiyana malinga ndi magawo a valavu. Chipata chikatsekedwa, zinthu za rabala zimamatira mwamphamvu ku mpando wa valavu chifukwa cha kusintha kwa elastic, zomwe zimapangitsa kuti zitsekedwe ndipo sizitulutsa madzi.

Kugwiritsa ntchito chitsulo chopopera kumapereka mphamvu zabwino zamakaniko komanso kukana dzimbiri, pomwe ukadaulo wopopera wofewa umatsimikizira kuti valavu imagwira ntchito bwino komanso kuti ikhale ndi moyo wautali. Kuphatikiza apo, pansi pa thupi la valavu pali chitsulo chopopera chopopera chopopera.ma valve a chipata cha madziNthawi zambiri imapangidwa ndi pansi pathyathyathya kuti isasonkhanitse zinyalala, kuchepetsa kulephera kwa kutsegula ndi kutseka, ndikuwonetsetsa kuti madzi akuyenda bwino. Chitsulo cha valavu nthawi zambiri chimapangidwa ndi zisindikizo zitatu za O-ring kuti zichepetse kukana kukangana panthawi yosintha, kuonetsetsa kuti ntchito ndi yosavuta komanso kuti madzi asatuluke.

Zitsanzo za ntchito ya ductile chitsulo chofewa chisindikizomavavu a chipata cholimbam'moyo watsiku ndi tsiku, zinthu zotsatirazi zikuphatikizapo koma sizimangokhalapo:

1. Dongosolo la madzi: Ma valve ofewa otsekedwa bwino angagwiritsidwe ntchito m'mapaipi operekera madzi m'nyumba ndi m'nyumba zamalonda kuti azitha kuletsa kusokonezeka ndi kulumikizana kwa madzi, kuonetsetsa kuti dongosolo la madzi lili otetezeka komanso lodalirika.

2. Kusamalira zinyalala: M'malo oyeretsera zinyalala m'mizinda ndi m'mabotolo otulutsira madzi, ma valve ofewa otsekedwa amagwiritsidwa ntchito kulamulira ndikuwongolera kuyenda kwa zinyalala, kupewa kutuluka kwa zinyalala, komanso kusunga ukhondo wa chilengedwe.

3. Ntchito Yomanga: Pa ntchito yomanga, ma valve ofewa otsekedwa bwino angagwiritsidwe ntchito polumikiza ndi kuchotsa mapaipi akanthawi, zomwe zimathandiza kuti madzi aziyenda bwino panthawi yomanga.

4. Dongosolo loteteza moto: Mu dongosolo lozimitsira moto lodzimitsira lokha, ma valve ofewa otsekedwa amagwiritsidwa ntchito poletsa ndikuwongolera momwe zinthu zilili pa payipi yayikulu kuti atsimikizire kuti madzi a moto akupezeka nthawi yake.

5. Ulimi wothirira: Mu njira zothirira m'minda, ma valve ofewa otsekedwa bwino angagwiritsidwe ntchito kulamulira kuyenda kwa madzi ndikuwonjezera kugwiritsa ntchito bwino madzi.

6. Ntchito zamafakitale: Mu njira zina zamafakitale, monga kukonza chakudya, kupanga mankhwala, ndi zina zotero, ma valve ofewa otsekereza amagwiritsidwa ntchito kuwongolera bwino kayendedwe ka madzi, kuonetsetsa kuti zinthu zili bwino komanso kuti zinthuzo ndi zotetezeka.

Valavu yofewa yotsekedwa ya flange yopangidwa ndi ductile ingathandize kuonetsetsa kuti mapaipi amagwira ntchito bwino komanso kupititsa patsogolo chitetezo cha uinjiniya, zomwe zimapangitsa kuti ikhale mtundu wa valavu yomwe imakondedwa kwambiri mumakina owongolera madzi. Ngati muli ndi zosowa zilizonse zofunika, chonde titumizireni uthenga pansipa ndipo mudzalandira yankho mkati mwa maola 24.
